ASPxGridView - After a grid filter, my groups don't stay expanded if the AutoExpandAllGroups property is true

I am grouping by a column (void field) and when the grid initially loads the two groups are expanded (if there is data for each group) which is correct. But if there are are no records in one of the groups, when i do another filter (by date in my example) the grouping type that had no records in its group before now will not be expanded even if it has records.
On my 1st screenshot, for that date, there were no voids, so the 'Voided: Yes' grouping is hidden. So when I filter by another date, 2nd screenshot, there are records in the 'Voided: Yes' grouping but the group is collapsed.
I have the AutoExpandAllGroups set to true in the grid and also have ASPxGridView1.SettingsBehavior.AutoExpandAllGroups = "true" set on the grid load.
Is there more I need to do to keep these groupings always expanded?
aspx:
<dxwgv:ASPxGridView Width="100%" ID="ASPxGridView1" runat="server"
        AutoGenerateColumns="False" DataSourceID="ObjectDataSource1"
        KeyFieldName="Receipt_No" >
…
  <SettingsBehavior AutoExpandAllGroups="true" />
aspx.vb:
Protected Sub ReceiptGrid_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
…
  If IsPostBack Then
            ASPxGridView1.SettingsBehavior.AutoExpandAllGroups = "true"
        End If
Hope I am making sense.
Thank you.
Steps to Reproduce:

run the project
filter the grid by setting the ProductId to 78
clear the filter

Hi Matt,
We've researched the problem and come to the conclusion that this behavior is by design. This property (AutoExpandAllGroups) is only applied if

the page is loaded for the first time and there is no post data;
grouping is changed.
If you want to have all groups to be always expanded, call the ASPxGridView.ExpandAll methods within the AfterPerformCallback event handler.
Thanks,
Plato

that worked great, I appreciate it. the code i used was
VB:
    Protected Sub ASPxGridView1_AfterPerformCallback(ByVal sender As Object, ByVal e As DevExpress.Web.ASPxGridView.ASPxGridViewAfterPerformCallbackEventArgs) Handles ASPxGridView1.AfterPerformCallback
        ASPxGridView1.ExpandAll()
    End Sub
